what does this function do? - dudaefj - 11.12.2013

PHP код:
stock fixmemset(aArray[], iValue, iSize = sizeof(aArray)) {
    new
        iAddress
    ;
    
    // Store the address of the array
    #emit LOAD.S.pri 12
    #emit STOR.S.pri iAddress
    
    // Convert the size from cells to bytes
    iSize *= 4;
    
    // Loop until there is nothing more to fill
    while (iSize > 0) {
        // I have to do this because the FILL instruction doesn't accept a dynamic number.
        if (iSize >= 4096) {
            #emit LOAD.S.alt iAddress
            #emit LOAD.S.pri iValue
            #emit FILL 4096
        
            iSize    -= 4096;
            iAddress += 4096;
        } else if (iSize >= 1024) {
            #emit LOAD.S.alt iAddress
            #emit LOAD.S.pri iValue
            #emit FILL 1024
            iSize    -= 1024;
            iAddress += 1024;
        } else if (iSize >= 256) {
            #emit LOAD.S.alt iAddress
            #emit LOAD.S.pri iValue
            #emit FILL 256
            iSize    -= 256;
            iAddress += 256;
        } else if (iSize >= 64) {
            #emit LOAD.S.alt iAddress
            #emit LOAD.S.pri iValue
            #emit FILL 64
            iSize    -= 64;
            iAddress += 64;
        } else if (iSize >= 16) {
            #emit LOAD.S.alt iAddress
            #emit LOAD.S.pri iValue
            #emit FILL 16
            iSize    -= 16;
            iAddress += 16;
        } else {
            #emit LOAD.S.alt iAddress
            #emit LOAD.S.pri iValue
            #emit FILL 4
            iSize    -= 4;
            iAddress += 4;
        }
    }
    
    // aArray is used, just not by its symbol name
    #pragma unused aArray
}
